So my poor Mid 2006 Mac Mini with Snow Leopard won't play back smoothly iPhone 4s video . I had previously already upgraded the memory to 2gb. Would I be able to get away with a Core 2 Duo 2.0 ghz upgrade? I'd rather not drop $100 on a 2.33ghz C2D if I could get by with a 2.0ghz C2D (around $35). Anyone have any experience with this or a similar macbook configuration? By not smoothly, I mean, it stutters and even pauses for a second or two and then skips ahead.
